User's Manual

To comply with FCC emission limits a ferrite core is supplied with the unit to be attached
close to the dc connector as described in figures 1 and 2. Attaching the ferrite core is
essential for the user's authority to operate the equipment.
Figure 1 shows the ferrite core open with two-turn coiling of the dc supply lines (one turn
means putting the lines straight into the ferrite, two turns means one additional loop). After
that the ferrite has to be closed. A click indicates proper locking. Figure 2 shows the closed
ferrite core attached to the dc supply lines.
